Plotly + Arduino Data Visualization

Plot.ly + Arduino Data Visualization

He have been a fan of Arduino for years now, and have used it for building everything from MIDI controllers to simple LED flashers. One thing that has always intrigued him has been visualizing some of the data that he read off of the Arduino Pins.

Plot.ly makes this simple. Really simple.

The purpose of this instructable is to demonstrate how to hook up an Arduino + Ethernet Shield and send data to Plot.ly’s Servers and create beautiful graphs. We will be using a dual temperature+humidity sensor (DHT22), and sending the results directly to Plotly.

Hardware:

• Arduino (We’re using the UNOr3)
• Ethernet Shield
• DHT22 Temperature + Humidity Sensor
• Hookup wires
• Angled pin headers (unless you use female-male hookup wires, then you won’t need these)
• 9v Wall Adapter
• Ethernet Cable

Software:
(We will explain how to install the libraries in a later step)

• Latest Arduino software (1.0.5)
• Plotly Arduino Library
• Adafruit DHT Arduino Library

Enclosure:

• Two pieces of (2 1/2″ x 3 1/2″ ) wood (1/4″ thick)
• Four (10-32x2in) Machine Screws
• 12 Hex Nuts (10-32 Diameter)
